Vulnerability discussion

The Iris Scanner allows a user to unlock a mobile device without entering a passcode when a registered user Iris is recognized. This technology would allow unauthorized users to have access to DoD sensitive data if compromised. By not permitting the use of non-password authentication mechanisms, users are forced to use passcodes that meet DoD passcode requirements.SFR ID: FMT_SMF_EXT.1.1 #23, FIA_UAU.5.1
